What to do if it is too late and you have fallen into the trap?
It can happen. You would not be the first or the last: this time you did not realise that it was an attempted fraud, you did what the message asked you to do. If you are in this situation, the most important thing is to acknowledge it, act calmly and with common sense, analysing what you have just done and act accordingly.
If you have provided your bank details (card number, PIN, CVV, coordinate card, etc.) the first thing you have to do is contact your bank and explain what happened so that they may take the appropriate reactive measures and mitigate the consequences of the phishing as much as possible. If you are a Santander customer, contact Superlínea as soon as possible on 915 123 123.
You must also act if, instead of bank details, what you have been asked for is other private information: contact the corresponding service and report the situation so that in the case of any problems, you can demonstrate that it was for this reason.
As a complementary measure, you should regularly monitor what the internet knows about you, to see if criminals are using this data without your consent. And in the case of bank accounts, it never hurts to check your movements frequently. This way you can detect any suspicious movements in time.
If your device has been infected, you will have to disinfect it. If you have problems in this, you can go to the OSI website where you will find very clearly explained steps that you must follow and they can also help you in this task by calling their support line on 017.
Finally, we recommend that you report the facts to the Police so that with all the evidence of the crime they can take the appropriate measures to hunt down cybercriminals.
